Remember several common positions of skull X-ray and work easily.

Those who have just studied medicine will make mistakes in judgment because they are not in place, which is not conducive to the diagnosis effect. Here are some common postures. Come and study.

0 1 positive head position:

Objective: To observe the bone, symmetry, bone plate thickness and intracranial conditions of the skull.

Photographic position: The patient is prone on the photographic bed, with the median sagittal plane perpendicular to the bed surface and coincident with the center line of the bed surface.

Midline: perpendicular to the eyebrows from the occipital eminence.

02 lateral head position:

Objective: To observe the shape, size and intracranial situation of skull, suture and sella turcica.

Photographic posture: The patient lies prone on the photographic bed, with his head turned sideways, his ears close to the table top, his upper limbs bent on his side, his elbow bent on the opposite side to support his lower jaw, and the line between pupils perpendicular to the bed surface.

Midline: 2.5cm in front of the external ear hole.

03 Tang's position:

Objective: To diagnose occipital squamous lesions (fracture, osteomyelitis, occipital hernia, etc.). ), foramen magnum lesions and petrous lesions of temporal bone (acoustic neuroma, cholesteatoma, etc. ).

Photographic position: the patient lies on his back on the photographic table with his arms at his sides; Then the sagittal plane of the patient's head is perpendicular to the bed surface and coincides with the center line of the cassette; The patient's mandible is adducted so that the auditory canthus line is perpendicular to the bed surface; The upper edge of the film is flush with the top of the head, and the lower edge is close to the lower jaw; Use filter or grating to shoot, and the shooting distance is 10O cm.

Midline: inclined to the foot side by 30? , about 10 cm above the eyebrow and below the occipital protuberance.

04 watt position:

Objective: To observe the bones and morphology of maxillary sinus, frontal sinus, ethmoid sinus and maxilla.

Photography position: The patient sits in front of the camera frame, holds the camera frame with both hands, raises his head back, and touches the cassette with his chin. The distance between the tip of the nose and the cassette is about 0.5~ 1.5cm, and the auditory canthus line is 37? Horn.

Midline: vertical injection through nasal root.

05 Coriolis position:

Objective: This position is the first choice for frontal sinus, ethmoid sinus diseases and retinoblastoma.

Photography location:

1. The client is prone on the photographic bed, with the median sagittal plane perpendicular to the bed surface and coincident with the center line of the bed surface.

2. The forehead and the tip of the nose are placed on the bed surface, the mandible is adducted, and the auditory canthus line is perpendicular to the bed surface.

Midline: incline to the foot at an angle of 23 degrees, and take the film through the nasal root.
